Ainu Nuye (애누이닥 누여)

Ainu Nuye is a method of writing Ainu using Korean hangul devised by Michael W. Ryan.
He sees the current script for writing the Ainu language
(modified Katakana) as a terrible writing system. He took (one of/) East Asia's
only alphabets, and the one which supports final sounds, and adapted it to Ainu.
This new writing system is based on Hangul and can be learned in a morning.
It is simple but intelligent, and its design fits with Han characters.
Michael leaves the rest of the credit to King Sejong. Nuye means 'to write'
in Ainu.
